The invention discloses an all-digital burr filter circuit, which comprises a handshake unit and a self-timing sequence delay unit, and is characterized in that the self-timing sequence delay unit comprises a self-timing sequence function unit and a delay unit; when an input signal is directly connected to one input port of the handshake unit, firstly passes through the self-timing sequence delay unit and then is connected to the other input port of the handshake unit, an effective input signal is regenerated at the output port of the handshake unit, and an ineffective input signal is filtered. On the basis, the all-digital burr filter circuit is realized by adopting an all-digital standard unit, has the advantages of standardization, cascade combination, adjustable filter range, low power and small occupied layout area compared with RC delay, and has the advantage of realizing long delay through a simple standard delay unit. 本发明公开一种全数字毛刺滤波电路，包括握手单元和自定时顺序延迟单元，其中，所述自定时顺序延迟单元包括自定时顺序功能单元和延迟单元；当输入信号直接连入所述握手单元的一个输
